There is a need for simple, light-weight practical instrumentation for rapid characterization of chemical and biological analytes in the modern battlefield. Recently, a surface-sensitive diode laser (SSDL), having over 1% of the mode power in the region extending 40 nm from the laser surface has been designed and fabricated. The SSDL was capable of monitoring the deposition of absorptive films a ...

Microwave resonators of linear dielectrics for wireless applications have been fabricated in bulk form using conventional ceramic processing in the current commercial market. Machining and fine polishing are frequently required for dimension control and surface finish in addition to the inherent unfeasibility to fabricate miniaturized electronic circuits. It is vital to develop a suitable thin f ...

Improved magnetic and electromagnetic sensors covering a wide range of frequencies, 0 to 10kHz, and with extremely high sensitivity are proposed for broad area detection and characterization of underground targets. The sensors can be used for a variety of applications and for different e.m. sources. They can be configured as gradiometers, as vector or scaler sensors and can be used as internette ...

The proof of concept research explores the potential for integrating the following four 'personal devices's () baseline IFF personal device () data applique interface to field processors () audio applique interface to voice headset or audio monitor () video applique interface to camera and display into a single, wearable non-line of sight spread spectrum IFF, tracking and duplex multimedia com ...

The Department of Defense has undertaken an ambitious environmental restoration program at thousands of facilities in the U.S. Many of these facilities have been contaminated by the discharge of dissolved heavy metals. Often these contaminants migrate into the ground water where they pose a serious threat to aquatic systems and to human health. The remediation of soils and ground water is usual ...

Many simulations environments, particularly those used for training purposes, employ simulated human behavior. To date, users frequently complain that such simulated behavior is not very intelligent and easy to "game" thus reducing the effectiveness of the training. We propose to improve intelligent agent technology through improved techniques for eliciting expert problem solving knowledge on wh ...

The number of mines buried throughout the world and the cost to remove them demonstrate an urgent need for field-deployable detection technologies. Current technologies being developed are large and not man-portable. Biosensors and immunoassay techniques are excellent detectors for these low vapor pressure explosive targets due to their inherent sensivity and specificity at the ppb and ppt level ...

This work offers an innovative approach to predicting system behavior (in terms of reliability and performance) based primarily on the structural characteristics of a formal functional specification. The mechanism for process composition is codified in the CSP-to-Stochastic Petri net (CSPN) toll. CSPN supports systematic specification, automatic translation and subsequent augmentation (e.g., fai ...

This program is directed towards developing catalytic membrane reactors for promoting the spontaneous conversion of logistic fuels to a gaseous feedstock compatible for subsequent introduction into the anode compartment of a solid oxide fuel cell (SOFC). These membranes behave as short circuited electrochemical cells with both ionic and electronic transport proceeding through the membrane bulk. ...
